Definitions

  • a passage 32 puts the upper chamber 2 in communication with the bottom of the well 27, whereto it opens with a bore or hole which is normally obstructed by a needle 33.
  • the needle is a downwardly extending integral portion of a small piston 34, which is arranged slidable vertically through the well 27 and overlying cap 35, which is formed from an insulating material and is attached to the pin 26 by means of a screw 36.
  • the bottom of the well 27 is vented to the outside through a hole 37 drilled diametrically to the pin 26.
  • the shutter 43 is moved to its open position: under the pressure raised in the chamber 2, the high temperature water contained in the chamber 1 flows over a conduit 10-29-41, and after passing the jet divider disk 20, flows through the powder contained in the cup 57 to produce the beverage by infusion, which flows out from the spout 54.
  • the beverage flows out at a high • concentration, and becomes gradually more diluted: as the powder is spent.
  • the more concentrated fractions may be separated by temporarily shutting off the water flow through the knob 47, such as to bring the shutter 43 to the shut off position; then, after placing fresh cups under the spout 54, the shutter can be re-opened.
